General Description

This is one of the animal virus genera in the family Reoviridae. Members have 11 genome segments and infect vertebrates. The name reflects the fact that virus particles have a wheel (latin Rota)-like appearance in electron microscopy.

Morphology

Virions isometric (icosahedral), c.100 nm in diameter, with three concentric capsid shells.

Genome

Linear, double stranded RNA in 11 segments. Each virion contains a single copy of the entire genome. Total genome c.18500 nucleotides long.

Genus Genomic Organization

Most segments have only one ORF.
